Groupon offers the factory-refurbished Ion Job Rocker Plus 50-watt Portable Wireless Bluetooth Speaker in Black or Orange, model no. IPA74, for $69.99 with free shipping. That's $15 under the lowest total price we could find for a new unit today, although we saw a refurb for $7 less in January. It features a 100-foot Bluetooth range, digital AM/FM radio, USB charging port, two AC power outlets, 1/4" microphone input, 3.5mm auxiliary input, rubberized buttons, wooden cabinet, steel handles, protective corner bumpers, and rechargeable battery. A 90-day Ion warranty applies. Deal ends April 11.
